CARD cLotueTINGr` FOR CARDING ENGINES.

Application led July 18, 1921, Serial No. 485,734. Renewed .Tune 17,1925.

To all whom t may concern:

Be it known that I, Pnosrnn OGER, a subject ot the King or' Belgium,residing at Roubaix, in thejRepublic of F rance, have invented new landuseful Improvements in Card r Clothing lforv Carding Engines, oi' whichthe lfollowing is a specilication.

This invention relates to the card clothing employed for the`4 rollersof carding engines, generally designated by the name 0i' llyers andthe:function of which is, as is welllrnown, to strip the cylinderl of thecarding engine.`

In card 'clothing' hitherto employed for the flyers of carding engines7the setting of the clothings is e'ii'ected parallel with the axis of theflyer, the hooks of the clothing being directed in planes at rightangles to the axis of the flyer. These clothings, by working between theclothingsot the cylinder, remove' more or` less' completely the wasteandmaterials which accumulate between the clothings of thel cylinder, butare unable vrto remove the waste and materials which lodgebetweentheteeth oi' the clothings of the cylinder, situated in the same plane. VIttherefore becomes necessary at certain times to stop the working of themachine in order to carry out a complete stripping of the cylinder. U

The present invention has forits principal object `to obviate thisdisadvantage, that is-to say to obtain a more complete stripping of theclothings of the cylinder by permitting the clothings of the'flyer toexercise their action evenbetween the teeth of the clothings of thecylinder situated in parallel planes at right angles to the axis of thecylinder. e

With this object in view my invention essentially consists ina specialarrangement of the hooks of the clothing of the flyer whereby the endsof the hooks are caused to act between the teeth placed in the sameplane on the cylinder, as will be hereinafter pointed out in theappended claims. p f* Referring to the annexeddrawing:

Fig. l shows diagrammatically the arrangement and mode of the settingemployed hitherto for the clothing of the iiyers and the cooperation ofthese clothings with those of the cylinder ot the carding engine.

Fig. 1a is a front view of a part of a clothing of the usualconstruction.

Fig. l? gives a'section taken on line A-B and Fig. lc a section on lineC-D in Fig. la.

Fig. 2 and Fig. 3 are longitudinal sections oit a flyer showingdiagrammatically the arrangement of the hooks of the clothings accordingto the invention. Fig. 2a is a iront .view of va part of a clotl ingprovided with the setting shown diagrammatically in Fig. 2.

Fig. 2b is asection taken on line E-F and Fig. 2c a section taken online G-H in Fig. 2a. Y l

Figs. 4. and 5 are front elevations of flyers showing the clothing onthe surface of said iiyers.

Figs. 6 and 7 show diagrammatically another mode ofthe setting which canbe used inthe arrangement shown in Figs. 2 to 5. Fig. 6"L is a frontview of a part of a cloth- Jling provided with. the setting shown inFig. b'is a section taken online I-J and Fig. 6c a'section taken onAline K-L in Fig. 6a.

In the ordinary clothing for flyers of carding 'engines, the settingiseffected, as is well known parallel with the axis of the flyer, or,in'other words a plurality of wires (Fig. l) provided with two'branchesb at right angles with a central part @are xed on or passed through aysupporting material 79 (Figs. la lb le), such as leather for nstance, insuch a mannerthat the branches project from the supporting .material giwhich is then placed on the surface of the yer with the central part aof the wires parallel with the axis of the flyer.

The projecting branches form then hooks b1 which are situated in planesparallel with each other and at right angles to the axis. -The resultisk that the points or teeth of the hooks b act solely between theparallel rows c formed by the hooks oiPA the clothing of the cylinder ofthe carding engine as shown diagrammatically in Fig. l (in which thepoints of the hooks of the clothing of the carding engine have beenshown) but'cannot 'exercise their actionin the spaces d comprisedbetween the successive points or teeth ci' the same row of the clothingof the cylinder.

This disadvantage is avoided, according to my invention by giving to thehooks bl a lateral inclination that is to say towards the right ortowards the left, with respect to the axis of the iiyer as is shown inFigures 2 and 3 which represent sections of the flyer e mounted on itsshaft f. Under these conditions the inclined hooks b1 penetrate into thespaces d (Figl.) of the clothing of the cylinder of the carding engineand are able to remove the waste and the materials which accumulateduring the working of the carding engine.

The two inclinations7 to the right and to the left may naturally becombined on the same flyer and the clotliings may be advantageouslyarranged in the form of chevrons g and' h adjacent to each other, asshown in Fifg. l or again in the form of chevrons leaving between themuncovered intervals i on the surface of the flyer as shown in Fig. 5.

Under these conditions, the lateral action, due to tlie inclinationbecomes reinforced, the stripped material having a tendency to collectat the ends of the flyer. ln practice, this action may be combined withato and fro movement of the flyer, from left to right and from right toleft.

The lateral inclination of the hooks b1 can be obtained by aid of theusual sett-ing as it is shown in Figs. 2 2b and 2C. In this case thecentral part a of the wire (Fig. 2a) extends longitudinally in contactwith the back of the supporting material p, parallel to the axis of theflyer upon which the clothing is placed, and the branches are passedthrough said supporting` material as .it is the case in Figs. lFL 1*"13but the hooks 1 ininstead of being formed in the same planes as the partb2 of the branches Z) which passes through the supportingl material y)and at right angles to the axis of the flyer are deflected laterally atb3 as it will appear from a comparison of Figs. 2a 2b and 2C in such amanner that the points or teeth of the hooks end in planes at rightangles to the axis of the flyer but parallel to the planes containingthe part b2 of the branches passing threugh the supporting material.

rlhe same result however can also be obtained with the form of hookedwires shown in Figs. lfL lb le, that is with the usual form of hookedwires by adopting the setting shown diagrammatically in Figs. 6 and 7which is effected at a suitable angle relatively to the axis of theflyer so that the teeth of the clothings hooked in the ordinary way areno longer situated in planes at right angles to the axis of the flyerbut rather in oblique planes parallel with each other. This mode ofsetting is further illustrated in F igs. 6, 6l and 6C. As it will appearfrom a comparison of the said figures, the central part a of the wire isagain placed on the back of the supporting material p but the. branchesb are passed through said supporting material on two parallel linestraced at different levels on the supporting material in such a. mannerthat the hooks b1 are directed laterally although being formed at rightangles to the central part a just like in the case shown in Figs. la 1bl".

lit should be noted that the arrangement described might be also carriedout by means of two cylinders covered with a strip of clothing formingvery pronounced spirals, one covering running towards the left and theother towards the right, and further that the arrangement may also becombined with the ordinary system of setting, the same cylinder or iyerbeing provided on its periphery with parts of clothing set in theordinary way (Figs. la lb, le) and parts set towards the left and right(Figs. 2 and 3) according to the effect desired to be obtained.

Vilhat l claim is:

l. Card clothing for fancy rollers of carding engines in which the teethof the rows running perpendicularly to the lateral edges of the fabricare inclined toward one ofthe said edges, whereby the said teeth areadapted to act between the teethY of the clothing of the main cylinderwhich are situated in parallel planes at right angles to the axis of themain cylinder of the cardingengine.

2. ln combination with a fancy roller of a carding engine, a cardclothing covering the said fancy roller, the said clothing comprisingrows of teeth, the points of the said teeth being inclined laterally inthe longitudinal diametral planes of the fancy roller containing thesaid .rows of teeth, whereby the said teeth are adapted to act betweenthe teeth of the clothing of the main cylinder which are situated inplanes parallel to each other but at right angles to the axis of themain cylinder of the carding engine.`

ln testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
